ESP8266 WiFi Bee is a compact serial-to-WiFi module designed based on XBEE, exuding elegance in its design. It caters to the wireless expansion needs of controllers like Arduino UNO and Leonardo, seamlessly fitting into the XBEE socket.

In the realm of DIY home IoT projects, wireless connectivity and remote control often become indispensable. However, the commonly used controllers like Arduino UNO and Leonardo do not integrate WiFi functionality by default. Therefore, the need arises to augment their capabilities with additional WiFi expansion boards or modules. Purchasing a separate controller with built-in WiFi functionality significantly escalates costs, while acquiring a WiFi expansion board engulfs a considerable amount of space. Although WiFi modules available in the market carry a lower price tag, their wiring and usage can be complex, coupled with a rather laborious AT programming process.

This ESP8266-based offering beautifully addresses the aforementioned quandaries. It boasts an embedded 32-bit processor, endowing it with formidable on-chip processing and storage capabilities. Adding to its prowess, the module encompasses the Lwip protocol stack, ensuring a stable and reliable wireless connection for you. The ESP8266 WiFi Bee supports three working modes: AP, STA, and AP+STA, all effortlessly configurable through AT commands. Simultaneously, it offers an Arduino ESP8266 library that seamlessly integrates with your familiar development environment, granting you unparalleled convenience in programming.

Moreover, this product adopts the XBEE design in its physical form, ensuring compatibility with the XBEE sockets found on the DF series Arduino UNO and Leonardo expansion boards. This thoughtful design choice simplifies usage and expedites the setup process. The onboard switch further simplifies module operation by allowing effortless selection between module functions or firmware upgrades.

Note: In order to configure this module, you will need an adapter or Xbee shield that lets you communicate with the module before you can plug it and use it on other modules. Compatible device: Xbee USB adapter (FTDI), Romeo V2 - a Robot Control Board with Motor Driver, XBoard V2 -A Bridge Between Home And Internet, Gravity: IO Expansion & Motor Driver Shield
